Title: Fuel reformer
Inventor: SHIMAZU TAKASHI
IPC: C01B3/38
Filed: 2001-04-10
Abstract: PROBLEM TO BE SOLVED: To provide a fuel reformer high in efficiency, simplified and compact in size by introducing steam into the reformed gas from a reformation/reaction part, mixing them homogeneously and supplying the mixed gas to a shift reaction part. SOLUTION: A heat exchange part 32 is constituted of the first heat exchange part 40 for exchanging heat between the reformed gas from the reformation/ reaction part and water, the second heat exchange part 50 for making water into steam by spraying to the reformed gas from the part 40 and the third heat exchange part 60 for vaporizing the unvaporized water. The reformed gas from the reformation/reaction part is cooled by the heat exchange when the water is heated at the part 40 and the heat of vaporization when the water is vaporized at the parts 50 and 60, mixed with the vaporized water and supplied to the shift reaction part as the mixed gas.  Since the cooling of the reformed gas, the heating and vaporizing of the water and the mixing of the reformed gas with the steam are completed in the part 32, this fuel reformer can be made to be high in efficiency, simplified and compact in size.

Title: Lock-up control device for torque converter
Inventor: TOYODA SHINYA
IPC: F16H59/18
Filed: 2001-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent lock-up from being released, even if switching to an engine brake range is performed during coast lock-up by making the capacity lower. SOLUTION: The capacity of a lock-up clutch of a torque converter during coast traveling at a D range is made to be conducted by front and rear differential pressure (PA-PR) of the lock-up clutch, corresponding to an absolute minimum coast lock-up capacity. When a driver performs a range switch to an L range by desiring the engine brake at a moment t1 , a control is switched from the coast lock-up control to a normal lock-up control and fastening capacity of the lock-up clutch is made a control maximum value. When performing the range switch during the coast traveling, the requested value of lock-up clutch fastening capacity rises, as shown by a broken line and reaches a peak at moment t3 . Because the control value of the lock-up clutch fastening capacity is also larger than the requested value at this peak time, a lock-up state can be maintained.
